Watch El-P Perform "Stay Down" On Letterman

This was last night's "Holy Shit!" moment on TV: El-P was on Letterman, performing "Stay Down" from his damn-near perfect Cancer for Cure. Let me repeat that: El-P was on Letterman last night. And he brought along a full band, and Nick Diamonds from Islands to do the track, and he even got a "I loved it! El-P is in the house!" from Paul. Did you ever think you'd see El-P crushing the shit out of Letterman's stage?
